Hello,
My problem is the short circuit, because I have try different values in the AFE SC Dsg Cfg register and I don't have different values with an oscilloscope.
For example:
with 0x77 programmed in AFE SC Dsg, of -450mV at the end of the shoet…
Other Parts Discussed in Thread: BQ3050 My BQ3050 is showing PCH status, but there's no precharge voltage driving the 300 ohm resistor. My PchgIn voltage is 15.2, but the PCR output isn't. I tried both 00 and 01 for the ZVCHG bit in Cfg A. My pack voltage…
Hello
I cannot to change the value of RSNS (or other) in the SMBus extended, I am in full access and unsealed access (I have access to data flash).
When i want write or read at 0x71 i have this error :
I don't understand, because I have access…
Other Parts Discussed in Thread: BQ3050 , BQEVSW Hi Ladies & Gents,
after calibration of bq3050 it is not possible to read the flash values from calibartion. It ends up with the message Runtime rerror '13', type mismatch. When verified this error message…
I'm changing an existing charger board to bigger batteries. Now the 3050 is dead. When I attach the batteries, both regulators are off. I'm assuming sleep mode. Turn on the pack voltage and the 3.3 is ok, but the 2.5 and RBI are still 0. How critical…

Does BQ3050 and its series IC`s have inbuilt charge algorithm ? When the Battery RSOC is around 5% , even we charging current of 800mA but Battery takes on around…
Part Number: BQ2085 Other Parts Discussed in Thread: BQ3050 , BQ25720 Hello Team ,
I am looking for Battery charger IC which Communicate Directly on SMbus without any host MCU to BMS based on BQ2085 / BQ3050....Any suggestion ?
Thanks in advance.…

Hello Team,
i noticed one problem is :
BQ starts accepting lower current than set after RSOC = 80%.
BQ Charging current drastically reduces after RSOC = 94% , it is around 50mA Only. FC is Set just at this RSOC. Takes So much…
Part Number: BQ2085 Other Parts Discussed in Thread: BQ3050 Hello Team ,
I am Designing BMS on two different ICs :
1. BQ2085
2. BQ3050
I need Help in Writing and Testing SMbus Firmware for It. Target Microcontroller is Arduino Atmega and PIC …
